A flow injection (FI) system is described for the sequential determination of periodate and
iodate based on their reaction with iodide at pH 3.5. Two sample plugs were injected into the
same carrier stream sequentially. One injection is for the iodate determination and the other
for the sum of iodate and periodate determination. For iodate determination, molybdate
solution buffered at pH of 3.5 was used for selective masking of periodate. The influences of
reagent concentrations were studied by a univariable method and the influence of FI ...
